Abstract: The present invention relates to a vertical landing apparatus for a flight vehicle and, more specifically, to a vertical landing apparatus for a flight vehicle, capable of enabling a flight vehicle such as a rocket or the like to safely and vertically land on the sea. According to one aspect of the present invention, the vertical landing apparatus for a flight vehicle includes a landing means and a support means. The landing means includes: a plurality of vertical bars placed with one planar end such that a flight vehicle can land vertically; a stopper guiding sliding such that the vertical bars can be slid only to a predetermined limit; and a plurality of elastic members having one end supporting the vertical bars and having the other end supporting the stopper. The support means has buoyancy to float on water while fixing the stopper. Further, the plurality of vertical bars are placed such that when a vertical bar where the flight vehicle has landed is slid due to the weight of the flight vehicle, a vertical bar adjacent to the sliding vertical bar can support the flight vehicle such that the flight vehicle does not fall. According to the present invention, when the flight vehicle lands vertically on the landing means, an adjacent vertical bar locks up the flight vehicle such that the flight vehicle does not get dislodged. Therefore, the present invention is capable of preventing the flight vehicle from being dislodged even when the flight vehicle is pitching due to waves.
